Hi Amanda

Sure you will all have a wonderful time. I agree with all the above, especially the part about having some relaxing days, park visiting is great fun but can be exhausting if it is very hot. One thing we have noticed about American theme parks is that they all seem to have plenty of water fountains around so make good use of them. As for shopping, if you want something in addition to outlet malls Florida Mall is the biggest. Your hotel reception will be able to give you directions.
Hope this is your first trip of many!
